Voltage Regulators AN77Lxx/AN77LxxM Series 3-pin, positive output, low dropout voltage regulator (100 mA type) Overview AN77Lxx series Unit: mm 5.00.2 4.00.2 The AN77Lxx series and the AN77LxxM series are stabilized constant voltage power supplies with a low in- put/output voltage difference (0.22V typ. for AN77L03). It is suitable for the low-voltage equipment using batter- 2.30.2 ies and consumer/industrial equipment with great fluc- 0.60.15 tuation of the supply voltage.
