L78L05

The L78L05 is designed as one kind of three-terminal positive regulators that are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Features of the L78L05 are:(1)output current up to 100 mA; (2)output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18; 20; 24V; (3)thermal overload protection; (4)short circuit protection; (5)no external components are required; (6)available in either ±5% (AC) or ±10% (C) selection.

The absolute maximum ratings of the L78L05 can be summarized as:(1)DC input voltage (Vo=3.3 to 9 V):30 V;(2)DC input voltage (Vo=12 to 15 V):35 V;(3)DC input voltage (Vo=18 to 24 V):40 V;(4)output current:100 mA;(5)power dissipation:internally limited;(6)storage temperature range:-40 to 150 °C;(7)operating junction temperature range:0 to 125 °C;(8)thermal resistance junction-case:20 (SO-8) or 15 (SOT-89)°C/W;(9)thermal resistance junction-ambient:55 (SO-8) or 200 (TO-92)°C/W.

And the electrical characteristics of the L78L05 can be summarized as:(1)output voltage:3.3 V;(2)line regulation (VI=5.3 to 20 V TJ=25°C):150 mV;(3)line regulation (VI=6.3 to 20 V TJ=25°C):100 mV;(4)dropout voltage:1.7 V;(5)supply voltage rejection:49 dB;(6)output noise voltage:40 uV.
