STC2G15
BCMOS VOLTAGE REGULATOR DESIGNED FOR USE WITH
VERY LOW ESR AND TANTALUM OUTPUT CAPACITOR
■
INPUT VOLTAGE FROM 2.7V TO 5.02V
■
■
■
STABLE WITH LOW ESR CERAMIC AND
TANTALUM CAPACITORS
VERY LOW QUIESCENT CURRENT (30µA
TYP. AT NO LOAD; 2µA IN OFF MODE)
GUARANTEED OUTPUT CURRENT UP TO
15mA
■
■
OUTPUT VOLTAGE: 1.5V
TSOT23-5L
LOGIC-CONTROLLED ELECTRONIC
SHUTDOWN
Shutdown Logic Control function is available, this
means that when the device is used as local
regulator, it is possible to put a part of the board in
standby, decreasing the total power consumption.
The STC2G15 is designed to work with low ESR
ceramic and tantalum capacitors. Typical
applications are in mobile phone, blue-tooth
module and similar battery powered wireless
systems.

INTERNAL CURRENT LIMIT
JUNCTION TEMPERATURE RANGE: -40°C
TO 95°C
DESCRIPTION
The STC2G15 provides up to 15mA, from 2.5V to
6V input voltage. The low quiescent current
makes it suitable for low power applications and in
battery powered systems.

Note 1:Time for the output Voltage to rise from 50% to 85% of nominal value.
Note 2: Time for the output Voltage to fall from 85% to 50 of nominal value.
Note 3: Regulator must be able to sustain Regulated Output Voltage without load.
Note 4: Parameters are uncritical as long as the output voltage stays within limits.
Note 5: A sudden voltage rise/drop of 500mV mustn't bring the output Voltage out of limits.
Note 6: Ceramic Capacitors can be used if connected between CMP pin and GNG, instead of V
Note 8: Maximum and minimum values are guaranteed in full temperature range.

Note 9: Line transient is tested when the input voltage changes from 2.7 to 3.2V in 10µs in full load range.
Note 10: Line transient is tested when the input voltage changes from 3.2 to 2.7V in 10µs in full load range.
Note 11: Load transient is tested when the load changes from 0.1 to 15mA in 10µs in all the input range
Note 13: Response time is defined as the time form the load line step until the output reaches a value within specification (1.41V, 1.59V).
Note 14: The maximum power dissipation for the operation depends on the ambient temperature.
For T =95°C, T =85°C and R =220°C/W the maximum power can be 0.045W. The maximum power dissipation for operation can be
