SNVS438B –APRIL 2007–REVISED DECEMBER 2007

LP5990 Micropower 200mA CMOS Low Dropout Voltage Regulator

Check for Samples: LP5990

FEATURES

DESCRIPTION

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

60 μV_RMSOutput Voltage Noise

60 μs Start-Up Time

When switched into shutdown mode via a logic signal

at the enable pin, the power consumption is reduced

to virtually

zero.

500μs Shut-Down Time

PSRR 55 dB at 10 kHz

Fast shut-down is achieved by the push pull

architecture.

Stable with 0402 1.0µF Ceramic Capacitors

Logic Controlled Enable

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.

Thermal–Overload and Short–Circuit

Protection

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

junction temperature range.

APPLICATIONS
