DESCRIPTION/ORDERING INFORMATION
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.
