† _{Across the full operating temperature, the minimum input voltage range for}
full output current is 4.3V to 26V. Output will remain in-regulation at lower
output voltages and low current loads down to an input of 2V at 25°C.
Electrical Characteristics
Limits in standard typeface are for T_J = 25°C and limits in boldface apply over the full operating temperature range. Unless otherwise
specified, V_IN = V_OUT + 1V, I_L = 1mA, C_L = 10µF. Adjustable versions are set for an ouptu of 5V. The MIC29202 V_SHUTDOWN ≤ 0.7V. The
eight pin MIC29204 is configured with the Adjust pin tied to the 5V Tap, the Output is tied to Output Sense (V_OUT = 5V), and V_SHUTDOWN ≤
0.7V.
