SP2526
Low ESR Cap. Compatible Positive Voltage Regulators
DESCRIPTION
The SP2526 family is a positive voltage linear
regulators, low power consumption, high voltage,
manufactured using CMOS technology. The SP2526
family provides large currents with a low dropout
voltage. The SP2526 consists of current limiter circuit,
driver transistor, precision reference voltage and error
correction circuit.
The SP2526 family is compatible with low ESR
capacitors. The current limiter's feedback circuit also
operates as a short protect for the output current
limiter. The SOT-23-3L / SOT-323 / SOT-353
packages are available for portable electronic
equipment.
FEATURES
