# Based on TI TPS7A4700 1A, 4.17-μVRMS, RF LDO Voltage Regulator
 
# Output Voltage Noise: 4.17 μVRMS (10 Hz, 100 kHz)

# Power-Supply Ripple Rejection: 82 dB (100 Hz) ≥ 55 dB (10 Hz, 10 MHz)

# Output Current: 1 A with Heat Sink

# Dropout Voltage: 307 mV at 1 A

# PCB Size = 6.35 x 4.0 cm

# Min DC Input Voltage = 5V, Max DC Input Voltage = 25V


Example DC Output Voltage Setting:

* All DIP Switch OFF = DC 1.4V, suggested DC input voltage = 3V - 5V

* All DIP Switch ON = DC 20.5V, suggested DC input voltage = 22v - 24V

* DC 3.3V = 1.4 + ( 1.6 + 0.2 + 0.1 ) V, suggested DC input voltage = 5V

* DC 5V = 1.4 + ( 3.2 +0.4 ) V, suggested DC input voltage = 6V - 7V

* DC 12V = 1.4 + ( 6.4 + 3.2 + 0.8 + 0.2 ) V, suggested DC input voltage = 14V - 18V

* DC 18V = 1.4 + ( 6.4 + 6.4 + 3.2 + 0.4 + 0.2 ) V, suggested DC input voltage = 24V


Note : If the difference of DC input voltage and DC output voltage is too large,
the chip & the heat sink will be very hot.
