78l05应用电路图

Adjustable Output Regulator

VOUT = 5V + (5V/R1 + IQ) R2
5V/R1 3 IQ, load regulation (Lr) » [(R1 + R2)/R1] (Lr of LM78L05)

Current Regulator

IOUT = (VOUT/R1) + IQ
IQ = 1.5 mA over line and load changes

5V, 500 mA Regulator with Short Circuit Protection

*Solid tantalum.
**Heat sink Q1.
***Optional: Improves ripple rejection and transient response.
Load Regulation: 0.6% 0 IL 250 mA pulsed with tON = 50 ms.

±15V, 100 mA Dual Power Supply
