These devices are capable of supplying 2 A of output current with a dropout of 210 mV (TPS75233, TPS75433). Quiescent current is 75 A at full load and drops down to 1 A when the device is disabled.TPS75201-Q1 and TPS754xx are designed to have fast transient response for larger load current changes.
Because the PMOS device TPS75201-Q1 behaves as a low-value resistor, the dropout voltage is very low (typically 210 mV at an output current of 2 A for the TPS75x33) 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 A over the full range of output current, 1 mA to 2 A). These two key specifications of TPS75201-Q1 yield a significant improvement in operating life for battery-powered systems.
The TPS75201-Q1 is enabled when the EN pin is connected to a low-level input 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 1 A at TJ = 25°C.
The RESET (SVS, POR, or power on reset) output of the TPS75201-Q1 initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS75201-Q1 monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.When the output reaches 95% of its regulated voltage, RESET goes to a high-impedance state after a 100-ms delay.RESET goes to a logic-low state when the regulated output voltage is pulled below 95% (i.e., over load condition) of its regulated voltage.
The TPS754xx has a power good terminal (PG) as an active high, open drain output, which can be used to implement a power-on reset or a low-battery indicator.
The TPS75201-Q1 or the TPS754xx are 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 1.5 V to 5 V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS75201-Q1 and the TPS754xx families are available in 20 pin TSSOP (PWP) packages.
