DATA SHEET www.onsemi.com Negative Voltage Regulators TO−220 T SUFFIX CASE 221AB 1.0 A Heatsink surface connected to Pin 2. MC7900 Series 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 V to − 24 V, these regulators employ current limiting, thermal shutdown, and safe−area compensation − making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess of 1.0 A. • No External Components Required • Internal Thermal Overload Protection • Internal Short Circuit Current Limiting • Output Transistor Safe−Area Compensation • Available in 2% Voltage Tolerance (See Ordering Information) • Pb−Free Package May be Available.

Output Gnd 2.0 k 1 R1 MC79XX Output CO** 1.0 mF A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V above more negative even during the high point of the input ripple voltage. XX, These two digits of the type number indicate nominal voltage. ** Cin is required if regulator is located an appreciable distance from power supply filter. ** CO improve stability and transient response. 1.6 k R2 VO 10 k ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 11 of this data sheet. 20 pF 10 pF 2.0 k 20 k 20 k 10 k 240 0.3 1.1 k 750 DEVICE MARKING INFORMATION See general marking information in the device marking section on page 12 of this data sheet.

Internal Short Circuit Protection that limits the maximum current the circuit will pass, and Output Transistor Safe−Area Compensation that reduces 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 long wire lengths, 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 mF or larger tantalum, mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The capacitor chosen should have an equivalent series resistance of less than 0.7 W. The bypass capacitor should be mounted with the shortest possible leads directly across the regulators 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. -20 V Input MC7905 10 IO = 200 mA R VO ≤ 10 V 2N3055* or Equiv 0.56 0.56 MJE200* or Equiv MC7905* 5.6 10 mF + Gnd + 1.0 mF + 1.0 mF + Gnd Figure 9. Current Boost Regulator (− 5.0 V @ 4.0 A, with 5.0 A Current Limiting) When a boost transistor is used, short circuit currents are equal to the sum of the series pass and regulator limits, which are measured at 3.2 A and 1.8 A respectively in this case. Series pass limiting is approximately equal to 0.6 V/RSC. Operation beyond this point to the peak current capability of the MC7905C is possible if the regulator is mounted on a heatsink; otherwise thermal shutdown will occur when the additional load current is picked up by the regulator. 1N4001G or Equiv +20 V Input 0.33 mF +15 V Output MC7815 + 1.0 mF 1.0 mF + Gnd 1.0 mF Gnd 1.0 mF *Mounted on heatsink. + + -5.0 V Output 0.56 Gnd 1.0 mF 1.0 mF + Clamp diode 1N4001G or Equiv Gnd 1N4001G or Equiv MC7915 -20 V Input Figure 8. Current Regulator The MC7905, −5.0 V regulator can be used as a constant current source when connected as above. The output current is the sum of resistor R current and quiescent bias current as follows: -15 V Output 1N4001G or Equiv Figure 10. Operational Amplifier Supply The MC7815 and MC7915 positive and negative regulators may be connected as shown to obtain a dual power supply for operational amplifiers. A clamp diode should be 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. 5.0 V IO + ) IB R The quiescent current for this regulator is typically 4.3 mA. The 5.0 V regulator was chosen to minimize dissipation and to allow the output voltage to operate to within 6.0 V below the input voltage. www.onsemi.com 9 MC7900 Series Protection Diodes Diode D2 prevents output capacitor from discharging thru the MC7915 during an input short circuit or fast switch off of power supply. When external capacitors are used with MC7900 series regulator it is sometimes necessary to add protection diodes to prevent the capacitors from discharging through low current points into the regulator or from output polarity reversals. Generally, no protection diode is required for values of output capacitance less then 10mF. Figure 11 shows the MC7915 with the recommended protection diodes. • Opposite Polarity Protection Diode D1 protects the regulator from output polarity reversals during startup, power off and short-circuit operation. • Reverse-bias Protection Gnd + 1.0 mF 1.0 mF Gnd + D1 MBRS140 or Equiv MC7915 -20 V Input -15 V Output D2 MBRS140 or Equiv Figure 11.
