NCP139: CMOS Linear Voltage Regulator with Bias Rail, 1 A Very Low Dropout
NCP139 is a 1 A VLDO equipped with NMOS pass
transistor and a separate bias supply voltage (VBIAS). The device
provides very stable, accurate output voltage with low noise suitable
for space constrained, noise sensitive applications. In order to
optimize performance for battery operated portable applications, the
NCP139 features low IQ consumption. The WLCSP6 1.2 mm x 0.8 mm
package is optimized for use in space constrained applications.
特性- Ultra-Low Dropout of Typ. 40mV
- Adjustable Voltage version
- 50 mV typical dropout at the full 1 A load.
- Guaranteed Output Current from 0 to 1 A
- 0.5% Typical Output Voltage Accuracy
- Output Current in Excess of 1 A
