快速瞬态响应1.5 -A低压差稳压器 FAST-TRANSIENT-RESPONSE 1.5-A LOW-DROPOUT VOLTAGE REGULATORS
The TPS753xxQ and TPS751xxQ devices 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 mV TPS75133Q, TPS75333Q. Quiescent current is 75 µA at full load and drops down to 1 µA when the device is disabled. These devices 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 mV at an output current of 1.5 A for the TPS75x33Q and is directly proportional to the output current. Additionally, because 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 mA 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 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 less than 1 µA at TJ = +25°C.
For the TPS751xxQ, the power-good terminal PG is an active high, open drain output for use with a power-on reset or a low-battery indicator.
The RESET SVS, POR, or power on reset output of the TPS753xxQ initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS753xxQ 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% that is, during an overload condition of its regulated voltage.
The TPS751xxQ and TPS753xxQ 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 TPS751xxQ and TPS753xxQ families are available in a 20-pin TSSOP PWP package.
