description

The TL750M and TL751M series are low-dropout positive voltage regulators specifically designed for
battery-powered systems. The TL750M and TL751M series incorporate onboard overvoltage and
current-limiting protection circuitry to protect the devices and the regulated system. Both series are fully
protected against 60-V load-dump and reverse-battery conditions. Extremely low quiescent current, even
during full-load conditions, makes the TL750M and TL751M series ideal for standby power systems.

The TL750M and TL751M series offers 5-V, 8-V, 10-V , and 12-V options. The TL751M series has the addition
of an enable (ENABLE) input. The ENABLE input gives the designer complete control over power up, allowing
sequential power up or emergency shutdown. When ENABLE
high-impedance state. The ENABLE input is TTL- and CMOS-compatible.

The TL750MxxC and TL751MxxC are characterized for operation over the virtual junction temperature range
0°C to 125°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. Maximum power dissipation is a function of TJ(max),

ambient temperature is PD = (TJ(max) – TA)/
variation in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be
activated at power levels slightly above or below the rated dissipation.

2. The package thermal impedance is calculated in accordance with JESD 51.
