This (TPS76850) combination provides high performance at a reasonable cost. • 2% Tolerance Over Specified Conditions for Fixed-Output Versions Since the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically • Open Drain Power Good (See TPS767xx for 230 mV at an output current of 1 A for the TPS76850) Power-On Reset With 200-ms Delay Option) and is directly proportional to the output current. • Ultralow 85 μA Typical Quiescent Current Additionally, because the PMOS pass element is a • Available in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, voltage-driven device, the quiescent current is very 3.0-V, 3.3-V, 5.0-V Fixed Output and low and independent of output loading (typically Adjustable (1.2 V to 5.5 V) Versions 85 μA over the full range of output current, 0 mA to 1 A). These two key specifications yield a significant • Fast Transient Response improvement in operating life for battery-powered • Thermal Shutdown Protection systems. This LDO family also features a shutdown • SOIC-8 (D) and TSSOP-20 (PWP) Package 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. Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery indicator.
