SIMD1 / Solar Regulator

Published:2013/7/3 2:25:00 Author:muriel | Keyword: SIMD1, Solar Regulator

The SIMD1 was enhanced in the Solar Regulator version which supplies a constant 2V after triggering and permits driving LEDs without using current limiting resistors with constant brightness. Note that you can use this Low Drop Out (LDO) linear regulator for various applications but like all linear regulators it is lossy . This is not a problem for controlling LEDs since they would otherwise use lossy resistors but for motors it is a different story. Try this new SIMD1 / Solar Voltage Regulator for use with blinking LED circuits (pummers). It turns on when it gets dark, just like a D1 but the output voltage is regulated to about 2V (depending on the reference LED Vf). The SIMD1 / solar regulator circuit draws no current during charging and when turned on, it draws less than 100uA with a maximum 10ma output current. The regulator provides constant LED brightness during the discharge and turns off when 1F solar capacitor voltage drops below the LED turn on voltage. The LED used for voltage reference in the solar regulator feedback loop and the LEDs used for the flasher must be the same high efficiency type to match the forward voltage specs. This circuit is ideal for supplying voltage to a Bicore or 74HC14 LED flasher since it eliminates the LED current limiting resistors and greatly reduces current consumption of the HC flasher circuits.
