TPS7A11 500-mA, Low V_IN, Low V_OUT, Ultra-Low Dropout Regulator

1 Features

3 Description

•

Ultra-low input voltage range: 0.75 V to 3.3 V

Ultra-low dropout for minimum power loss:

– 140 mV (maximum) at 500-mA DRV package

– 110 mV (maximum) at 500-mA YKA package

Low quiescent current:

The TPS7A11 is an ultra-small, low quiescent current,

low-dropout regulator (LDO). This device can source

500 mA with an outstanding ac performance (load and

line transient responses). This device has an input

range of 0.75 V to 3.3 V, and an output range of 0.5 V

to 3.0 V with a very high accuracy of 1.5% over load,

line, and temperature. This performance is ideal for

supplying power to the lower core voltages of modern

microcontrollers (MCUs) and analog sensors.

•

– V_INI_Q= 1.6 µA (typical)

– V_BIASI_Q= 6 µA (typical)

•

1.5% accuracy over load, line, and temperature

High PSRR: 64 dB at 1 kHz

Available in fixed-output voltages:

– 0.5 V to 3.0 V (in 50-mV steps)

V_BIASrange: 1.7 V to 5.5 V

The primary power path is through the IN pin and can

be connected to a power supply as low as 140 mV

above the output voltage. This device supports very

low input voltages with the use of an additional V_BIAS

rail that is used to power the internal circuitry of the

LDO. The IN and BIAS pins consume very low

quiescent current of 1.6 µA and 6 µA, respectively.

The low I_Qand ultra-low dropout features help to

increase the efficiency of the solution in power-

sensitive applications. For example, the supply

voltage to the IN pin can be an output of a high-

efficiency, DC/DC step-down regulator and the BIAS

pin supply voltage can be a rechargeable battery.

2 Applications

•

Smart watches, fitness trackers

Wireless headphones and earbuds

Camera modules

Smart phones and tablets

Portable medical devices

Solid state drives (SSDs)

The TPS7A11 is equipped with an active pulldown

circuit to quickly discharge the output when disabled,

and provides a known start-up state.

The TPS7A11 is available in a small 2.00-mm × 2.00-

mm WSON, 6-pin (DRV) package and an ultra-small

0.74-mm × 1.09-mm, 5-pin DSBGA (YKA) package

that makes the device suitable for space-constrained

applications.
