NCP139中文资料LDO Regulator with Bias Rail and Very Low Dropout, 1 A数据手册ONSEMI规格书

描述 Description

NCP139 is a 1 A LDO 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 Features

• Ultra-Low Dropout of Typ. 40mV
• Allows to save power and operates with very low Vin-Vout voltage.
• Adjustable Voltage version
• Excellent choice for low voltage Vcore applications
• 50 mV typical dropout at the full 1 A load.
• minimizes the power loss across the regulator
• Guaranteed Output Current from 0 to 1 A
• Very good choice for high current applications
• 0.5% Typical Output Voltage Accuracy
• Perfect fit for POL applications
• Output Current in Excess of 1 A
• Output Active Discharge option available

应用 Application

• Battery - powered and Portable Equipment
• Smartphones, Tablets
• Cameras, DVRs, Camcorders
