(S) MOTOROLA MC7900 Series THREE-TERMINAL - NEGATIVE VOLTAGE REGULATORS The MC7900 Series of fixed output negative voltage regulators are intended as complements to the popular MC7800 Series devices. These negative regulators are available in the same seven-voltage options as the MC7800 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative MC7900 Series. Available in fixed output voltage options from ~5.0 to 24 volts, these regulators employ current limiting, thermal shut- down, and safe-area compensation making them remarkably rugged under most operating conditions. With adequate heat- sinking they can deliver output currents in excess of 1.0 ampere. @ No External Components Required THREE-TERMINAL NEGATIVE FIXED VOLTAGE REGULATORS @ @ Internal Thermal Overload Protection Gnd Output (nternal Short-Circuit Current Limiting K SUFFIX @ Output Transistor Safe-Area Compensation METAL PACKAGE @ Available in 2% Voltage Tolerance (See Ordering Information} CASE 1-03 (Bottom View) T SUFFIX SCHEMATIC DIAGRAM PLASTIC PACKAGE CASE 221A-04 Gnd 2k 2k ak PIN 1.

The measurement is made under conditions of low dissipation or by using pulse techniques such that the average chip temperature is not significantly affected. Load Regulation -- The change in output voltage for s change in load current at constant chip temperature. Maximum Power Dissipation - The maximum total device dissi- pation for which the regutator will operate-within specifications. Input Bias Current - That part of the input current that is not delivered to the load. Qutput Noise Voltage - The rms ac voltage at the output, with constant load and no input ripple, measured over a specified fre- quency range. Long Term Stability - Output voltage stability under sccelerated life test conditions with the maximum rated voltage listed in the devices etectrical characteristics and maximum power dissipation. APPLICATIONS INFORMATION Dasign Considerations The MC7900 Saries of fixed voltage reguistors are designed with Thermal Overload Protection that shuts down the circust when subjected ta an excessive power overload condition, Internat Short-Circuit Protection that limits the maximum current the cir- cuit will pass, and Output Transistor Safe-Area Compensation that reducas the output short-circuit current as the voltage across the pass transistor is increased. in many low current applications, compensation capacitors are not required. However, it is recommended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with tong wire tengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good high-frequency characteristics to insure stable operation under all load conditions. A 0.33 uF or larger tantalum, mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the reg- ulators input. terminals. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. Bypassing the output is also recommended. FIGURE 8 CURRENT REGULATOR -20V 10 1g = 200 mA Input MC7906 OF "8 _ g Vo 10V 1.0 MF 1.0 uF vO tO Gnd e + @ Gnd The MC7905,-5.0 V reguistor can be used as a constant current source when connected as above. The output current is the sum of resistor A current and quiescent bias current as follows: 5.0V lo= t'8 The quiescent current for this regulator is typically 4.3 mA. The 5.0 volt regulator was chosen to minimize dissipation and to allow the output voltage to operate to within 6.0 V below the input voltage.

Gnue Tt Ty ecna - *Mounted on common heat sink, Motorola MS-10 or equivatent. When a boost transistor is used, short-circuit currents are equal to the sum of the series pass and regulator limits, which are massured at 3.2 A and 1.8 A respectively in this case. Series pass limiting is approximataly equal to 0.6 V/Agc. Operation beyond this point to the peak current capability of the MC7905C is pos- sible if the ragulator is mounted an a heat sink; otherwise thermal shutdown will occur when the additional load currant is picked up by the regulator. 422 FIGURE 10 OPERATIONAL AMPLIFIER SUPPLY (15 V@ 1.0 A) +20 V +15 V Input Gutput mMc7a815 Gnd Gna + 1.0 WF 1.0 pF | MC7915 ot. -20V -168 V input Output The MC7815 and MC7915 positive and negative regulators may be connected a4 shown to obtain a dual power supply for oper- atlanal amplifiers. A clamp diode should ba used at the output of the MC7815 to prevent potential latch-up problems whenever the output of the positive regulator (MC7815) is drawn below ground with an output current greater than 200 mA.SECTION 19 T-40-20 PACKAGE OUTLINE DIMENSIONS K SUFFIX METAL PACKAGE CASE 1-03 Raja = 45C/W (TYP) (TO-3) NOTES: 1, DAAMETER AHD SURFACE W ARE DATUMS.
