The HT4936S is a monolithic, mobile power management chip that uses advanced charge-and-discharge port sharing and synchronous rectification with low external components and excellent performance. Form a good 1A-in / 1A-out 4LEDs mobile power.



1. Built-in maximum 1A linear charging mode, charging current adjustable externally;
2. trickle / constant current / constant voltage three-stage charging, 4.20V / 4.35V optional support 0V battery charge;
3. built-in charging can automatically reduce the charging current according to temperature rise, 130 degrees began to decline, the minimum can be reduced to 0;
4.step-up using synchronous rectification circuit, the highest efficiency over 90%, low heat, fixed 5.1V output, do not need external Resistance setting
5. Boost output current 1A (BTP = 3.6V);
6.With constant power output function, a complete over current, short circuit protection, built-in temperature protection automatically stop temperature rise over-temperature;

LM78L05 Datasheet PDF – 5V Positive Regulators – TI

Part Number : LM78L05

Function : 3-Terminal Positive Regulators

Manufacturers : Texas Instruments

LM78L05 Pinout image


The LM78LXX series of three terminal positive regulators is available with several fixed output voltages making them useful in a wide range of applications. When used as a zener diode/resistor combination replacement, the LM78LXX usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment.
