Datasheet BA10SFP DatasheetBA10SFP Datasheet (PDF)

Regulator ICs BAΟΟST / BAΟΟSFP series Regulator, low drop-out type with ON/OFF switch BAΟΟST / BAΟΟSFP series The BAΟΟST and BAΟΟSFP series are variable, fixed output low drop-out type voltage regulators with an ON/OFF switch. These regulators are used to provide a stabilized output voltage from a fluctuating DC input voltage. Fixed output voltages are 3.3V, 5V, 6V(SFP), 7V, 8V, 9V, 10V(ST), 12V(ST). The maximum current capacity is 1 A for each of the above voltages. !Application Constant vol.
