IC 3.3V 150MA LDO REG SOT-23-5 - TPS76333DBVR - Integrated Circuits
by Kenny Lee Attention electronics The TPS763xx 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 5-terminal small outline integrated-circuit SOT-23 package, the TPS763xx 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 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 (TPS76333)—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 mA 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 also features a logic-enabled
sleep mode to shut down the regulator, reducing quiescent current to 1
mA maximum at TJ = 25°C.The TPS763xx is offered in 1.6-V,1.8-V, 2.5-V,
2.7-V, 2.8-V, 3.0-V, 3.3-V, 3.8-V,and 5-V fixed-voltage versions and in a
variable version (programmable over the range of 1.5 V to 6.5 V.
