TEXAS INSTRUMENTS TPS75515KTTT. 固定电压稳压器, LDO, 2.8V至5.5V, 250mV压差, 1.5V输出, 5A输出, TO-263-5
The TPS755xx family of 5-A low dropout LDO regulators contains four fixed voltage option regulators with integrated power-good PG\\\\ and an adjustable voltage option regulator. These devices are capable of supplying 5 A of output current with a dropout of 250 mV TPS75533. Therefore, the device is capable of performing a 3.3-V to 2.5-V conversion. Quiescent current is 125 uA at full load and drops down to less than 1 uA when the device is disabled. The TPS755xx 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 250 mV at an output current of 5 A for the TPS75533 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 uA 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\ enable shuts down the regulator, reducing the quiescent current to less than 1 uA at TJ = 25°C. The power-good terminal PG\\\\ is an active low, open drain output, which can be used to implement a power-on reset or a low-battery indicator.
The TPS755xx 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 TPS755xx family is available in a 5-pin TO\x96220 KC and TO\x96263 KTT packages.
