产品详情

Demonstration circuit 1855A is a dual, micropower, low noise and low dropout voltage linear regulator featuring the LT3030. The input voltages are independent for each channel of DC1855A and can range from 2.2V to 20V. Each channel has a jumper that sets the output voltage to either 1.5V, 1.8V, 2.5V, 3.3V, 5V or a voltage that is user-programmed by the installation of a resistor. For channel 1 and channel 2, the maximum output currents are 750mA and 250mA and the ceramic output capacitors are 22μF and 10μF respectively. The internal reference of each channel is bypassed with a 10nF capacitor for reduced output noise. Each channel has a jumper for shutdown and a terminal for PWRGD that is pulled up to the input supply. A resistor divider can be easily added that allows precise lockout at low input voltages.
