TPS75125-EP
TPS75125-EP is FAST-TRANSIENT-RESPONSE 1.5-A LOW-DROPOUT VOLTAGE REGULATORS manufactured by Texas Instruments.
- Part of the TPS75101-EP comparator family.
- Part of the TPS75101-EP comparator family.
TPS751xx Q are low dropout regulators with integrated power-on reset and power-good (PG) functions respectively. These devices are capable of supplying 1.5 A of output current with a dropout of 160 m V (TPS75133Q, TPS75333Q). Quiescent current is 75 µA at full load and drops down to 1 µA when the device is disabled. TPS751xx Q and TPS753xx Q are designed to have fast transient response for larger load current changes.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 160 m V at an output current of 1.5 A for the TPS75x33Q) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 75 µA over the full range of output current, 1 m A to 1.5 A). These two key specifications yield a significant improvement in operating life for battery-powered systems.
The device is enabled when EN is connected to a low level voltage. This LDO family also Features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at TJ = 25°C.
For the TPS751xx Q, the power-good terminal (PG) is an active high, open drain output, which can...
