description
The TPS764xx family of low-dropout (LDO) voltage regulators offers the benefits of a low noise, low-dropout
voltage, low-power operation, and miniaturized package. Additionally, they feature low quiescent current when
compared to conventional LDO regulators. Offered in 5-terminal small outline integrated-circuit SOT-23
package, the TPS764xx series devices are ideal for low-noise applications, cost-sensitive designs and
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 very low—typically 300 mV at 150 mA of load current (TPS76433)—and is directly
proportional to the load current. Since the PMOS pass element is a voltage-driven device, the quiescent current
is very low (140
μ
A 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 TPS764xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current
to 1
