SM2930-33
250mA Fixed Low Dropout
Elektronische Bauelemente
RoHS Compliant Product
Voltage Regulator
SOT-89
Description
The SM2930-33 is a positive voltage output, three-pin regulator which
provides high output current even when the input/output voltage
differential is small. The SM2930-33 consists of a high-precision
voltage reference, an error amplification circuit, and a current limited
output driver.
