DESCRIPTION
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.

FUNCTIONAL DESCRIPTION
1. Basic Operation
The UTC L1136‘s block diagram is shown in the following. (Fig.1)
The UTC L1136 has an error amplifier, and it compares the reference voltage (VREF) with VFB, which is the
output voltage resistance-divided by feedback resistors RS and RF. It supplies the gate voltage necessary to
maintain the constant output voltage which is not influenced by the input voltage and temperature change, to the
output transistor.

2. Output Transistor
For L1136, the output transistor is a P-channel MOSFET with low on-resistance.
In order to protect against inverse current, make sure that VOUT does not exceed VIN+0.3V, because of a
parasitic diode between the VIN and VOUT pin, when the potential of VOUT became higher than VIN.
3. Shutdown Pin (ON/OFF pin)
The shutdown pin is used to turn on and turn off this regulator.
When the ON/OFF pin is set to the shutdown level, the entire internal circuit stops operating. For reducing the
current dissipation, the internal P-channel MOSFET is shut down. The VOUT pin is set to the VSS level by the internal
dividing resistor of several hundred kΩ between the VOUT and VSS pin.
Note: When the ON/OFF pin voltage is in the range of 0.3V~1.0V, the current dissipation increases. The
architecture of the ON/OFF pin can be seen in Fig. 2 Since the ON/OFF pin is neither pulled down nor pulled up
internally, do not use it in the floating state.

FUNCTIONAL DESCRIPTION (Cont.)
4. Over-current protection circuit
An over-current protection circuit is contained in the UTC L1136. It aims at preventing the output transistor from
damage due to an excessive output current and short circuiting between the VOUT and VSS pin. The current (ISHORT) is
internally-fixed to about typically 200mA when short-circuit condition is applied in output pin, and the initial value is
restored for the output voltage, if releasing a short circuit once.
Caution: This over-current protection circuit does not work as for thermal protection. If this IC maintains short
circuiting for a long time inside, take care to the conditions of input voltage and the load current, therefore,
under the usage conditions including short circuit, the IC’s consumption will not exceed power dissipation
of the package.
5. Thermal shutdown circuit
A thermal shutdown circuit is included to prevent this device from being damaged for overheat. The thermal
shutdown circuit operates to stop regulating when the junction temperature becomes higher than 150°C (TYP.), and
it turns back to normal operation when the junction temperature is lower than 120°C (TYP.).
Due to self-heating of the UTC L1136, if the thermal shutdown circuit starts operating, it stops regulating so that
the output voltage drops. When the regulating operation stops, the IC’s temperature goes down due to the UTC
L1136 does not generate heat itself. When the temperature drops, the thermal shutdown circuit is released to restart
regulating, thus this IC generates heat again. Repeating this procedure makes waveform of the output voltage
pulse-like form. Stop/Restart of regulation continues unless decreasing either/both of the input voltage and the
output voltage for reducing the internal current consumption, or decreasing the ambient temperature.

6. Rush current control circuit
The rush current control circuit is designed to protect against the rush current occurs during power-on or when
the ON/OFF pin is ON. The rush current is specified to typically 400mA immediately after power-on or from the
ON/OFF pin is ON until the specified time (100μs min.) which is set internally.
Caution: Due to the thermal shutdown protection circuit, the junction temperature drops to 120°C (TYP.), after
stopping regulation, the circuit is released to restart regulation; in this case, pay attention to the period
which is to limit rush current to be shorter (10μs min.).
UTC assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or
other parameters) listed in products specifications of any and all UTC products described or contained
herein. UTC products are not designed for use in life support appliances, devices or systems where
malfunction of these products can be reasonably expected to result in personal injury. Reproduction in
