DESCRIPTION/ORDERING INFORMATION
TL750L, TL751L SERIES
LOW-DROPOUT VOLTAGE REGULATORS
SLVS017S – SEPTEMBER 1987 – REVISED AUGUST 2005
• 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
• Internal Overcurrent-Limiting Circuitry
TL751L Series
• Less Than 500- µ A 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.
