description
The TL750L and TL751L series and the TL751L05M and TL751L12M 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 both itself
and the regulated system. Both series and the TL751L05M and TL751L12M are 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.
The TL750L series of fixed-output voltage regulators offer 5-V, 8-V, 10-V, and 12-V options. They are available
in TO-226AA (formerly TO-92) (LP) packages, TO-220AB (KC) packages, 8-pin small-outline plastic packages
(D), and 8-pin plastic dual-in-line packages (P).
The TL751L series of fixed-output voltage regulators offer 5-V, 8-V, 10-V, and 12-V options with the addition of
an enable input. The enable input, when taken high, places the regulator output in a high-impedance state. This
gives the designer complete control over power up, power down, or emergency shut down. This series is offered
in the 8-pin small-outline plastic package and the 8-pin plastic dual-in-line package.
The TL751L05M and TL751L12M fixed-output voltage regulators also offer 5-V and 12-V options with an enable
input. The enable input, when taken high, places the regulator output in a high-impedance state. This gives the
designer complete control over power up, power down, or emergency shut down. This TL751L_M is offered in
the FK and JG package.
