Voltage Regulators AN79Lxx/AN79LxxM Series 3-pin negative output voltage regulator (100 mA type) Overview AN79Lxx series Unit: mm 5.00.2 4.00.2 The AN79Lxx series and the AN79LxxM series are 3-pin, fixed negative output type monolithic voltage regulators. Stabilized fixed output voltage is obtained from un- 2.30.2 stable DC input voltage without using any external compo- 0.60.15 nents. 12 types of output voltage are available: 4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V and 24V. They can be used widely in power circuits with current capacity of up to 100mA. +0.1 +0.1 0.43 0.43 0.05 0.05 2.54 Features 1 : Output No external components 2 : Common 213 3 : Intput Output voltage: 4V, 5V, 6V, 7V, 8V, 9V,10V, SSIP003-P-0000 12V, 15V, 18V, 20V, 24V Built-in overcurrent limit circuit AN79LxxM series Unit: mm 1.6 max.
