3 Description
The TPS763xx-Q1 family of low-dropout (LDO) voltage regulators offers the benefits of low-dropout voltage, low-power operation, and miniaturized packaging. These regulators feature low dropout voltages and quiescent currents pared to conventional LDO regulators. Offered in a 5-pin, small outline integrated-circuit SOT-23 package, the TPS763xx-Q1 series devices are ideal for costsensitive designs and for applications where board space is at a premium.
A bination of new circuit design and process innovation has enabled the usual pnp pass transistor to be replaced by a PMOS pass element. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage is low- typically 300 m V at 150 m A of load current (TPS76333-Q1)- and is directly proportional to the load current. Since the PMOS pass element is a voltage-driven device, the quiescent current is low (140 μA maximum) and is stable over the entire range of output load current (0 m A to 150 m A). Intended for use in portable systems such as laptops and cellular phones, the low-dropout voltage feature and low-power operation result in a significant increase in system battery operating life.
The TPS763xx-Q1 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 μA maximum at TJ =...
