78L05 D D D D D D 3-Terminal Regulators Output Current up to 100 mA No External Components Internal Thermal-Overload Protection Internal Short-Circuit Current Limiting Provided Pb-Free packages from the end of 2004 Positive-Voltage Regulators 78L05ACZ-Bulk 78L05ACZM-Ammo SO-8 78L05ACM O C I TO-92 INPUT COMMON OUTPUT description This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power-pass elements to make high-current voltage regulators. One of these regulators can deliver up to 100 mA of output current. The internal limiting and thermal-shutdown features of these regulators make them essentially immune to overload. When used as a replacement for a zener diode-resistor combination, an effective improvement in output impedance can be obtained, together with lower bias current. www.DataSheet.co.kr OUTPUT GND INPUT SOT-89 78L05CPK electrical characteristics at specified virtual junction temperature, VI = 10 V, Io= 40 mA (unless otherwise noted) PARAMETER TEST CONDITIONS TJ‡ MIN V to 20 V to 40 mA 7Vt I 1 mA At A Io=1mA to 40MA, V =7V to20V 25°C Full range Full range 25°C C 25 f = 120 Hz 25°C 41 4.8 4.75 4.75 78L05 TYP 5 MAX 5.2 5.25 5.25 150 100 60 30 UNIT Output voltage 5 V Input voltage regulation Ripple rejection Output voltage regulation Output noise voltage Dropout voltage IO = 1 mA to 70 mA VI = 7 V to 20 V VI = 8 V to 20 V VI = 8 V to 18 V, 5 32 26 49 15 8 42 1.7 3.8 mV mV dB mV mV µV V IO = 1 mA to 100 mA IO = 1 mA to 40 mA f = 10 Hz to 100 kHz 25°C 25°C 25°C 25°C 125°C Bias current Bias current c rrent Bias current change VI = 8 V to 20 V IO = 1 mA to 40 mA 6 5.5 1.5 0.1 mA mA mA mA Full Full F ll range ‡ Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. All characteristics are measured with a 0.33-µF capacitor across the input and a 0.1-µF capacitor across the output. Full range for the 78L05 is T J = 0°C to 70°C 1 Datasheet pdf – http://www.DataSheet4U.net/ 78L05 Positive-Voltage Regulators absolute maximum ratings over operating temperature range (unless othewise noted) 78L05 voltage, VI Input voltage Virtual junction temperature range, TJ Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds Storage temperature range, Tstg PARAMETER UNIT V °C °C °C 30 150 260 –65 to 150 recommended operating conditions 78L05 voltage VI Input voltage, MIN MAX UNIT 7 20 100 V mA Output current, IO Operating g virtual j junction temperature, TJ 0 70 °C Pad Location 78L 05 www.DataSheet.co.kr 9 9 Chip size 0.75 x 0.8 mm Pad N 1 2 3 Pad Name Ground Input Output X (um) 63 595 63 Y (um) 63 645 645 2 Datasheet pdf – http://www.DataSheet4U.net/ 78L05 Positive-Voltage Regulators […]
