DESCRIPTION/ORDERING INFORMATION

TL750L, TL751L SERIES

LOW-DROPOUT VOLTAGE REGULATORS

SLVS017T – SEPTEMBER 1987 – REVISED AUGUST 2007

• Very Low Dropout Voltage, Less Than 0.6 V at

• Reverse Transient Protection Down to –50 V

150 mA

• Internal Thermal-Overload Protection

• Very Low Quiescent Current

• Overvoltage Protection

• TTL- and CMOS-Compatible Enable on TL751L

• Internal Overcurrent-Limiting Circuitry

Series

• Less Than 500-μA Disable (TL751L Series)

• 60-V Load-Dump Protection

The TL750L and TL751L series of fixed-output voltage regulators offer 5-V, 8-V, 10-V, and 12-V options. The

TL751L series also has an enable (ENABLE) input. When ENABLE is high, the regulator output is placed in the

high-impedance state. This gives the designer complete control over power up, power down, or emergency

shutdown.

The TL750L and TL751L series are low-dropout positive-voltage regulators specifically designed for

battery-powered systems. These devices incorporate overvoltage and current-limiting protection circuitry, along

with internal reverse-battery protection circuitry to protect the devices and the regulated system. The series is

fully protected against 60-V load-dump and reverse-battery conditions. Extremely low quiescent current during

full-load conditions makes these devices ideal for standby power systems.
