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

and the high-efficiency that results from the
regulator鈥檚 ultralow power operation make the

TPS76201 especially useful in handheld and
portable battery applications. This regulator

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
碌A(chǔ)
maximum) and is stable over the entire range of output load current (10
碌A(chǔ)
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
