DESCRIPTION
The TPS76201-Q1 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 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 compared 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 combination 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 mA maximum)
and is stable over the entire range of output load
current (10 mA 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-Q1 also features a logic-enabled
sleep mode to shut down the regulator, reducing
quiescent current to 1 mA typical at T_J = +25°C. The
TPS76201-Q1 is offered in an adjustable version
(programmable over the range of 0.7 V to 5.5 V).
