description
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.
The TL750L and TL751L series of fixed-output voltage regulators offers 5-V, 8-V, 10-V, and 12-V options. The
TL751L series has the addition of 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.

†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 af fect device reliability.
NOTES: 1. The transient input voltage rating applies to the waveform shown in Figure 1.
2. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability.
3. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.

§Pulse-testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal ef fects must
be taken into account separately . All characteristics are measured with a 0.1-µF capacitor across the input and a 10-µF capacitor, with equivalent
series resistance of less than 0.4 Ω, across the output.
TJ(min) is 0°C for the TL75xLxxC devices, and –40°C for the TL75xLxxQ devices.
NOTE 4: For TL750L05Q/TL751L05Q, all characteristics are measured with a 0.1-µF tantalum capacitor on the output with equivalent series
resistance within the guidelines shown in Figure 4.
