Introduction

AI Translation

The TPS757xx family of 3-A low dropout (LDO) regulators contains four fixed voltage option regulators with integrated power-good (PG（overline）) and an adjustable voltage option regulator. These devices are capable of supplying 3 A of output current with a dropout of 150 mV (TPS75733). Therefore, the device is capable of performing a 3.3 V to 2.5 V conversion. Quiescent current is 125 μA at full load and drops down to less than 1 μA when the device is disabled. The TPS757xx is designed to have fast transient response for large load current changes.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 150 mV at an output current of 3 A for the TPS75733) 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 125 μA over the full range of output current). 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（overline） (enable) shuts down the regulator, reducing the quiescent current to less than 1 μA at TJ = 25 ℃. The power-good terminal (PG（overline）) is an active low, open drain output, which can be used to implement a power-on reset or a low-battery indicator.

The TPS757xx is offered in 1.5-V, 1.8-V, 2.5-V, and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.22 V to 5 V). Output voltage tolerance is specified as a maximum of 3% over line, load, and temperature ranges. The TPS757xx family is available in a 5-pin TO–220 (KC) and TO–263 (KTT) packages.

The TPS757xx family includes four fixed-output voltage regulators (1.5 V, 1.8 V, 2.5 V, and 3.3 V), and an adjustable regulator, the TPS75701 (adjustable from 1.22 V to 5 V). The bandgap voltage is typically 1.22 V
