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. TPS75233-Q1 and TPS754xx are designed to have fast transient response for larger load current changes.
Because the PMOS device TPS75233-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 TPS75233-Q1 yield a significant improvement in operating life for battery-powered systems.
The TPS75233-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 of TPS75233-Q1 (SVS, POR, or power on reset) output of the TPS752xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS752xx 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 of TPS75233-Q1 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 TPS75233-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 TPS75233-Q1 and the TPS754xx families are available in 20 pin TSSOP (PWP) packages.
