LP5990

Micropower 200mA CMOS Low Dropout Voltage Regulator

General Description

Features

The LP5990 regulator is designed to meet the requirements

of portable, battery-powered systems providing an accurate

output voltage, low noise and low quiescent current.

Operation from 2.2V to 5.5V input

■

±1% accuracy over temp range

Output voltage from 0.8V to 3.6V in 50mV increments

The LP5990 will provide a 1.8V output from a low input voltage

of 2.2V and can provide 200mA to an external load.

30 μA Quiescent current (enabled)

10nA Quiescent current (disabled)

160mV dropout at 200mA load

■

When switched into shutdown mode via a logic signal at the

enable pin, the power consumption is reduced to virtually

60 μV_RMSOutput voltage noise

60 μs start-up time

500μs shut-down time

zero.

Fast shut-down is achieved by the push pull architecture.

The LP5990 is designed to be stable with space saving 0402

ceramic capacitors as small as 1µF, this gives an

overall solution size of < 2.5mm ².

PSRR 55 dB at 10 kHz

Stable with 0402 1.0µF ceramic capacitors

Logic controlled enable

Performance is specified for a -40°C to 125°C junction tem-

perature range.

Thermal–overload and short–circuit protection

The device is available in micro SMD Package (0.4mm pitch)

and is available with 1.2V,1.3V,1.8V,2.8V,3.0V,3.3V and 3.6V

outputs.Lower voltage options down to 0.8V are available on

request. For all other output voltage options please contact

your local NSC sales office.

Package

4-Bump micro SMD,0.4mm

pitch

866 µm x 917 µm

(lead free)

Applications

Cellular phones
