1 / 16 page TPS76201 LOW OUTPUT ADJUSTABLE ULTRALOW POWER 100mA LDO LINEAR REGULATOR SLVS323B − FEBRUARY 2001 − REVISED JANUARY 2007 1 D 100-mA Low-Dropout Regulator D Adjustable Output Voltage (0.7 V to 5.5 V) D Only 23 µA Quiescent Current at 100 mA D 1 µA Quiescent Current in Standby Mode D Over Current Limitation D −40°C to 125°C Operating Junction Temperature Range D 5-Pin SOT-23 (DBV) Package description The TPS76201 low-dropout (LDO) voltage regulator features an adjustable output voltage as low as 0.7 V. 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 regulator’s ultralow power operation make the TPS76201 especially useful in handheld and portable battery applications. This regulator features low dropout voltages and ultralow quiescent current compared to conventional LDO regulators. Offered in a 5-terminal small outline integrated-circuit SOT-23 package, the TPS76201 is ideal for micropower operations and where board space is at a premium. A combination of new circuit design and process innovation has enabled the usual PNP pass transistor to be replaced by a PMOS pass element. Since the PMOS pass element is a voltage-driven device, the quiescent current is ultralow (30 µA maximum) and is stable over the entire range of output load current (10 µA to 100 mA). 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 also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 1 µA typical at TJ = 25°C. The TPS76201 is offered in an adjustable version (programmable over the range of 0.7 V to 5.5 V).
