L1136 Datasheet


The UTC L1136 is an extremely low dropout regulator providing
designers with low current dissipation, high output voltage accuracy
and it is developed based on CMOS technology.
The internal transistor with low-resistance provides small
dropout voltage and the large output current. Various capacitors, as
well as small ceramic capacitors, can be used for this IC more than
for the conventional regulator ICs which have CMOS technology.
The ON/OFF circuit can guarantee longer sure the battery life.
    The over-current protection circuit is designed to protect the device from being damaged because of load
current while exceeding the capacitance of output transistor. The thermal shutdown protection circuit protects
against heat and the rush current control protection circuit and limits the excessive rush current during start-up.
The UTC L1136 is universally suitable for power supply of battery-powered devices, power supply of TV,
notebook PCs and home electric appliances, and constant-voltage power supply of portable equipment.

* Output Voltage Ranges from 1.0 to 5.0V Selectable in 0.05V Step  
* Input Voltage Varies From 1.5 to 5.5V  
* Low Equivalent Series Resistance Capacitor:
Ceramic Capacitor of 4.7μF or More can be used as the I/O Capacitor
* High Accuracy Output Voltage: ±1.0%(1.0~1.45V output product: ±15mV)
* Low Current Consumption:   
 During operation: 70μA (TYP.), 90μA (MAX.) (3.0V output product)
During shutdown: 0.1μA (TYP.), 1.0μA (MAX.)
* Low Dropout Voltage:     
70mV (TYP.) (3.0V output product, at IOUT = 200mA)
* Output current:    
 600mA (3.0V output product, at VINVOUT(S)+1.0V) 
(Attention should be paid to the power dissipation of the package when the output current is large.)
* High ripple rejection:      70dB (TYP.) @ 1.0kHz, VOUT=1.0V
* Internal Protection Circuits:
 Over-Current Protection Circuit, Thermal Shutdown Circuit And Rush Current Control Circuit
* Internal Power On/Off Circuit Ensures Longer Battery Life
* Special Care should be Taken to the Power Consumption of the Package when the Output Current is Large.
