This • Low-Dropout Voltage: 230 mV typical at 1 A combination provides high performance at a (TPS76850) reasonable cost. • 2% Tolerance Over Specified Conditions for Since the PMOS device behaves as a low-value Fixed-Output Versions 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 voltage-driven device, the quiescent current is very • Available in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, low and independent of output loading (typically 3.0-V, 3.3-V, 5.0-V Fixed Output and 85 µA over the full range of output current, 0 mA to Adjustable (1.2 V to 5.5 V) Versions 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 mode; applying a TTL high signal to EN (enable) • SOIC-8 (D) and TSSOP-20 (PWP) Package shuts down the regulator, reducing the quiescent current to less than 1 µA at T J = 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. Figure 1.
