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 is high, the regulator output is placed in the
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), 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. Due to
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.

PARAMETER MEASUREMENT INFORMATION
The TL751Mxx is a low-dropout regulator. This means that the capacitance loading is important to the performance
of the regulator because it is a vital part of the control loop. The capacitor value and the equivalent series resistance
(ESR) both affect the control loop and must be defined for the load range and the temperature range. Figures 1 and 2
can establish the capacitance value and ESR range for the best regulator performance.
Figure 1 shows the recommended range of ESR for a given load with a 10-µF capacitor on the output. This figure
also shows a maximum ESR limit of 2 Ω and a load-dependent minimum ESR limit.
For applications with varying loads, the lightest load condition should be chosen because it is the worst case. Figure 2
shows the relationship of the reciprocal of ESR to the square root of the capacitance with a minimum capacitance
limit of 10 µF and a maximum ESR limit of 2 Ω. This figure establishes the amount that the minimum ESR limit shown
in Figure 1 can be adjusted for different capacitor values. For example, where the minimum load needed is 200 mA,
Figure 2 suggests an ESR range of 0.8 Ω to 2 Ω for 10 µF. Figure 2 shows that changing the capacitor from 10 µF
to 400 µF can change the ESR minimum by greater than 3/0.5 (or 6). Therefore, the new minimum ESR value is 0.8/6
(or 0.13 Ω ). This allows an ESR range of 0.13 Ω to 2 Ω , achieving an expanded ESR range by using a larger capacitor
at the output. For better stability in low-current applications, a small resistance placed in series with the capacitor (see
Table 1) is recommended, so that ESRs better approximate those shown in Figures 1 and 2.
