It is an ideal regulator for sub 1.2-V DSP core voltage supplies and is equally suited for similar applications with other low-voltage processors and controllers. SOT-23 packaging and the high-efficiency that results from the ultralow power regulator operation make the TPS76201-Q1 especially useful in handheld and portable battery applications. This regulator features low dropout voltages and ultralow quiescent current pared to conventional LDO regulators. Offered in a five-terminal, small outline integrated circuit (SOT-23) package, the TPS76201-Q1 is ideal for micropower operations and 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 is a voltage-driven device, the quiescent current is ultralow (30 m A maximum) and is stable over the entire range of output load current (10 m A to 100 m A). Intended for use in portable systems such as laptops and cellular phones, the ultralow-power operation results in a significant increase in the system battery operating life. The TPS76201-Q1 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 m A typical at TJ = +25°C. The TPS76201-Q1 is offered in an adjustable version (programmable over the range of 0.7 V to 5.5 V). Ground...
