Key Specifications
Product Description
The UM142xx series are a group of positive voltage output, high precise, high PSRR and low power consumption voltage regulator. The output voltages are selectable in 100mV steps within a range of 2.5V to 5V. It also can be customized on command.
The UM142xx series have excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system.
The UM142xx series are available in a low profile SOT23-3& SOT89-3 package, which are lead (Pb)-free.
Features
- Low Quiescent Current: 8μA at 5V
- High PSRR: 60dB Range to 10kHz
- Low Output Noise: 44μVRMS
- Low Dropout: 270mV at 150mA Load
- Low Temperature Coefficient: ±100ppm/°C
- Excellent Line Regulation: 0.05%/V
Typical Application Circuit
Note 1: Input Capacitor (CIN=1μF) is recommended in all applications.
Note 2: Output Capacitor (COUT=1μF/6.8μF) is recommended in all applications to assure the stability of circuit. 1μF Tantalum capacitor or 6.8μF ceramic capacitor is recommended.
