NCP137: CMOS Linear Voltage Regulator with Bias Rail, 700 mA Very Low Dropout
NCP137 is a 700 mA 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
NCP137 features low IQ consumption. The WLCSP6 1.2 mm x 0.8 mm
package is optimized for use in space constrained applications.
Features- Ultra-Low Dropout of Typ. 40mV
- Adjustable Voltage version
- 40 mV typical dropout at the full 700 mA load.
- Guaranteed Output Current from 0mA to 700mA
- 0.5% Typical Output Voltage Accuracy
- Output Current in Excess of 700mA
- Output Active Discharge option available
| Benefits- Allows to save power and operates with very low Vin-Vout voltage.
- Excellent choice for low voltage Vcore applications
- minimizes the power loss across the regulator
- Very good choice for high current applications
- Perfect fit for POL applications
