VOUT has a tolerance of less than 1% and is temperature pensated. Fixed output voltages 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, 3.3V, and 5.0V and an adjustable version are available in a small 5-pin SOT-23 package. Other key features include zero off-mode current, reverse battery protection, thermal shutdown and current limit. The SPX5205 is an excellent choice for use in batterypowered applications, and where power conservation is desired such as: cellular/ cordless telephones, radio control systems, and portable puters. ..net TYPICAL APPLICATION CIRCUIT VOUT 2 + GND 3 EN ENABLE may be tied directly to VIN SPX5205 + 1.0μF BYP (Optn) TOP View Exar Corporation 48720 Kato Road, Fremont CA, 94538 - (510) 668-7000 - FAX (510)...
