Additional Information

Negative LDO Voltage Regulators

Features:
- 5% output accuracy over entire operating range
- Output current in excess of 1A
- Dropout voltage typically 0.6V at 1A load
- Low quiescent current
- Internal short circuit current limit
- Internal thermal shutdown with hysteresis
- Functional complement to the LM2940 series

Electrical Characteristics
(VIN = −5V + VO(NOM), IO = 1A, CO = 47 μF, TJ=25C unless otherwise noted):

Output Voltage (5mA ≤ IO ≤ 1A): -12.0V typ.
Line Regulation (IO = 5mA, VO(nom) -1V VIN > -26V): 6.0mV typ.
Load Regulation (50 mA ≤ IO ≤ 1A): 3.0mV typ.
Dropout Voltage (IO = 0.1A, ΔVO ≤ 100 mV): 0.1V typ.
Quiescent Current (IO ≤ 1A): 1mA typ.
Short Circuit Current (RL = 1Ω): 1.2A typ.
Maximum Output Current: 1.8A typ.
Ripple Rejection: 52dB
Output Noise Voltage (10 Hz100 kHz, IO = 5 mA): 500uV typ.

Applications
- Post switcher regulator
- Local, on-card, regulation
- Battery operated equipment
