description
The TPS72xx family of low-dropout (LDO) voltage
regulators offers the benefits of low-dropout
voltage, micropower operation and miniaturized
packaging. These regulators feature extremely
low dropout voltages and quiescent currents
compared to conventional LDO regulators.
Offered in small-outline integrated-circuit (SOIC)
packages and 8-terminal thin shrink small-outline
(TSSOP), the TPS72xx series devices are ideal
for cost-sensitive designs 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 device.
Because the PMOS pass element behaves as a
low-value resistor, the dropout voltage is very low
– maximum of 85 mV at 100 mA of load current
(TPS7250) – and is directly proportional to the
load current (see Figure 1). Since the PMOS pass
element is a voltage-driven device, the quiescent current is very low (300
μ
A maximum) and is stable over the
entire range of output load current (0 mA to 250 mA). Intended for use in portable systems such as laptops and
cellular phones, the low-dropout voltage feature and micropower operation result in a significant increase in
system battery operating life.
The TPS72xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current
to 0.5
μ
A maximum at T
J
= 25
°
C. Other features include a power-good function that reports low output voltage
and may be used to implement a power-on reset or a low-battery indicator.
The TPS72xx is offered in 3.3-V, 4.85-V, and 5-V fixed-voltage versions and in an adjustable version
(programmable over the range of 1.2 V to 9.75 V). Output voltage tolerance is specified as a maximum of 2%
over line, load, and temperature ranges (3% for adjustable version).
