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 compared to
conventional LDO regulators. Offered in a 5-pin, small
outline integrated-circuit SOT-23 package, the
TPS763xx-Q1 series devices are ideal for cost-
sensitive designs and for applications 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 behaves as a low-value
resistor, the dropout voltage is low—typically 300 mV
at 150 mA 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
mA to 150 mA). 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 = 25°C.The
TPS763xx-Q1 is offered in 1.6-V,1.8-V, 2.5-V, 3-V,
3.3-V, and 5-V fixed-voltage versions and in a
variable version (programmable over the range of 1.5
V to 6.5 V).
