The MAX857ESA+T from Analog Devices (formerly Maxim Integrated) is a high-efficiency, CMOS step-up DC-DC switching regulator designed for small, low input voltage or battery-powered systems. It accepts input voltages from 0.8V and can generate adjustable output voltages in the range of 2.7V to 6.0V.
Key features include a typical efficiency of 85% at 100mA, a low quiescent current of 25µA, and a shutdown mode current of 1µA. The device incorporates an internal MOSFET power transistor, enabling high switching frequencies up to 500kHz. This, combined with internally set peak inductor current limits, allows for the use of small, low-cost inductors. The MAX857ESA+T has a 500mA switch-current limit.
This regulator is suitable for applications requiring 3.3V to 5V step-up conversion, such as palmtop computers, portable data-collection equipment, personal data communicators, medical instrumentation, and 2-cell or 3-cell battery-operated devices like glucose meters.
The MAX857ESA+T is available in an 8-pin SOIC package and is designed for surface mounting. It operates within a temperature range of -40°C to 85°C.
