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.

PARAMETER MEASUREMENT INFORMATION
The TL750L, TL751L series are low-dropout regulators. This means that capacitance loading is important to the
performance of the regulator because it is a vital part of the control loop. The capacitor value and its equivalent
series resistance (ESR) both affect the control loop and must be defined for the load range and temperature
range. Figure 1 shows the recommended range of ESR for a given load with a 10- µ F capacitor on the output.
