Specifications subject to change without notice.
Note 1: SG2003 series’ output current is 400mA peak.
Note 2: The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT + 1V.
(Only applicable for VOUT = +2.5V to +4.5V)
Note 3: Time needed for VOUT to reach 95% of final value.
