1 / 17 page SM72238 www.ti.com SNVS694C – JANUARY 2011 – REVISED APRIL 2013 Micropower Voltage Regulator Check for Samples: SM72238 1 FEATURES DESCRIPTION The SM72238 is a micropower voltage regulator with 2 • Renewable Energy Grade very low quiescent current (75µA typ.) and very low • High-Accuracy Output Voltage dropout voltage (typ. 40mV at light loads and 380mV • Ensured 100mA Output Current at 100mA). It is ideally suited for use in battery- powered systems. Furthermore, the quiescent current • Extremely Low Quiescent Current of the SM72238 increases only slightly in dropout, • Low Dropout Voltage prolonging battery life. • Extremely Tight Load and Line Regulation The SM72238 is available in the surface-mount D- • Very Low Temperature Coefficient Pak package. • Use as Regulator or Reference Careful design of the SM72238 has minimized all • Needs Minimum Capacitance for Stability contributions to the error budget. This includes a tight • Current and Thermal Limiting initial tolerance (.5% typ.), extremely good load and line regulation (.05% typ.) and a very low output • Stable With Low-ESR Output Capacitors voltage temperature coefficient, making the part (10m Ω to 6Ω) useful as a low-power voltage reference.
