Voltage Regulators AN78Lxx/AN78LxxM Series 3-pin positive output voltage regulator (100 mA type) Overview AN78Lxx series Unit: mm 5.00.2 4.00.2 The AN78Lxx series and the AN78LxxM series are 3- pin fixed positive output type monolithic voltage regula- tor. A stabilized fixed output voltage is obtained from an 2.30.2 unstable DC input voltage without using any external 0.60.15 parts. 12 types of fixed output voltage are available 4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V and 24V. They can be used widely as power circuits with a current capacity of up to 100mA. +0.1 +0.1 0.43 0.43 0.05 0.05 2.54 Features 1: Input No external components 2: Output 213 3: Common Output voltage: 4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, SSIP003-P-0000 18V, 20V, 24V Built-in overcurrent limit circuit AN78LxxM series Unit: mm 1.6 max.
