Uses LM376N positive voltage regulator in switching mode to compensate for voltage changes of battery sup-ply during discharge cycle, without adjusting series rheostat. Load regulation is 0.3% for un-regulated input of 9 to 30 V, with R1 and R2 setting output voltage anywhere between 5 and 27 V. Maximum output current is 25 mA. Switching frequency of regulator is 33 kHz. -E. R. Hnatek and L. Goldstein, Switching Regulator Designed for Portable Eqiupment, EDN|EEE Magazine, Sept. 15, 1971, p 39-41.
