Ultra Low Noise (4/16µVRMS) Dual Polarity Power Supply
Positive Rail, 1.4V – 20.5V, 1A
Negative Rail, -3V – -18V, 1A
- Input Voltage Range : +3VDC to +25VDC, 3VAC to 18VAC
- Output Voltage Noise: Positive Rail 4μVRMS (10 Hz, 100 kHz)/Negative Rail 16μVRMS (10 Hz, 100 kHz)
- Power-Supply Ripple Rejection:
– 82 dB (100 Hz)/72 dB (10 kHz)
– ≥ 55 dB (10 Hz, 10 MHz) - ANY-OUT™ Voltage Modes:
– User-Programmable Output via Solder pads on LDOVR PCB
– Output Voltage Range: +1.4 V to +20.5 V (0.1V step) for Positive Rail and -3Vto -18V for Negative Rail (1V step) - Output Current: 1A
- Dropout Voltage: 307 mV at 1A
- CMOS Logic Level-Compatible Enable Pin, if enable is not required, tie EN to Vin (J4,J8)
- External Sense Input - This pins must be connected to OUT, can be connected to the point of load to maximize accuracy, tie S+ to Vout+ and S- to Vout- if external connection not used (J3,J7)
- Built-In Fixed Current Limit and Thermal Shutdown
- PCB size: 60x60mm
- Operating Temperature Range:–40°C to 125°C
