GENERAL DESCRIPTION
It has an internal deglitch circuit for filtering the noise of the EN input. The SGM3132 requires only a 35mV dropout voltage at a 20mA load. The feature makes SGM3132 ideal for battery-operated systems, such as personal digital assistants. The SGM3132 is available in Green TQFN-3×3-16L, TDFN-2×2-8L and MSOP-8 packages and is specified over an ambient temperature range of -40℃ to +85℃.FEATURES
