GENERAL DESCRIPTION
AX1110 is guaranteed to have lower than 1.2V dropout at full load current making it ideal to provide well-regulated outputs of 1.25 to 5.0 with 6.4V to 12V input supply. FEATURES
- 1.2V maximum dropout at full load current - Fast transient response - Output Current Limiting - Built-in Thermal Shutdown - Good noise rejection - 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V, 3.3V, 5.0V - Packages: SOT-23-3L BLOCK DIAGRAM VÛmw`R●yÑb€ Vin w.goftechm + + CURRENT LIMIT 1.25V Vout + GND (FIXED) + Thermal Shutdown - Adj 1/6 Axelite Confidential Materials, do not copy or distribute without written consent. Rev.1.6 Dec.14, 2011 AX1110 PIN ASSIGNMENT The package of AX1110 is SOT-23-3L; the pin assignment is given by: Name DESCRIPTION
A resistor divider from this pin to the Adj VOUT pin and ground sets the output (GND) voltage. (Ground only for Fixed-Mode) The input pin of regulator. Typically a large storage capacitor (0.15 Ω ≤ ESR ≤ 20Ω) is connected from this pin to ground to insure that the input voltage does not sag below the VIN minimum dropout voltage during the load transient response.
