Product Description
 
The UM1450 series are a group of positive voltage output, high precise and low power consumption voltage regulators. The maximum input voltage is 16V. The output voltages are selectable in 100mV steps within a range of 2.5V to 5V. It can also be customized on command.
The UM1450 series have very low power consumption (IQ=2μA) which can greatly improve natural life of batteries.
The UM1450 series are available in a low profile SOT23-3 & SOT89-3 packages, which are lead (Pb)-free.
 
Features

- Low Dropout:
  210mV@100mA (VOUT=3.3V)
  420mV@200mA (VOUT=3.3V)
- Low Temperature Coefficient: ±150ppm/°C
- Output Current Limit:
  330mA@ VOUT=3.3V
 
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.
 
Applications
 
- Battery-Powered Equipment
- Power Management of MP3, PDA, DSC, Mouse, PS2 Games
- Reference Voltage Source
- Hand-Hold Equipment
