The output of the regulator. A minimum of 10uF capacitor (0.15Ω ≤ ESR ≤ 20Ω) must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a large storage capacitor (0.15Ω ≤ ESR ≤ 20Ω) is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response. This pin must always be 1.3V higher than VOUT in order for the device to regulate properly. 2 of 8 www.diodes.com FEBRUARY 2009 © Diodes Incorporated AP1115 0.6A LOW DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR Typical Circuit 5V 5V C1 100uF C1 100uF VIN VIN GND Adj VOUT VOUT 3.3V/0.5A C2 100uF AP1115 A (5V/3.3V Fixed Output) R1 121 Ω VO R2 121 Ω 2.5V/0.5A C2 100uF AP1115 A (5V/2.5V Adj Output) 5V 5V C1 100uF C1 100uF VO VOUT VOUT 3.3V/0.5A C2 100uF VIN 2.5V/0.5A C2 R1 121 Ω 100 uF VIN Adj GND R2 121 Ω AP1115 B (5V/3.3V Fixed Output) AP1115B (5V/2.5V Adj Output) Note : Vo = VREF x (1+ R 2 ) R1 Absolute Maximum Ratings Symbol VIN PD TST TMJ Parameter DC Supply Voltage Power Dissipation Storage Temperature Maximum Junction Temperature Rating -0.3 to 18 V Internally Limited -65 to +150 150 Unit V mW o C o C Recommended Operating Conditions Symbol TOP Parameter Operating Junction Temperature Range AP1115 Rev. 7 3 of 8 www.diodes.com Min 0 Max 125 Unit o C FEBRUARY 2009 © Diodes Incorporated AP1115 0.6A LOW DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR Electrical Characteristics (Under Operating Conditions) Parameter Reference Voltage AP1115-ADJ AP1115-1.5 AP1115-1.8 AP1115-2.5 AP1115-2.8 Output Voltage AP1115-3.0 AP1115-3.3 AP1115-3.5 AP1115-5.0 Line Regulation AP1115-XXX AP1115-ADJ AP1115-1.5 AP1115-1.8 AP1115-2.5 Load Regulation AP1115-2.8 AP1115-3.0 AP1115-3.3 AP1115-3.5 AP1115-5.0 Dropout Voltage (VIN-VOUT) Current Limit Minimum Load Current (Note 5) Thermal Regulation Notes: Conditions TA = 25oC, (VIN - OUT) = 1.5V IO = 10mA o IOUT = 10mA, TA = 25 C, 3V ≤ VIN ≤ 12V o IOUT = 10mA, TA = 25 C, 3.3V ≤ VIN ≤ 12V o IOUT = 10mA, TA = 25 C, 4V ≤ VIN ≤ 12V o IOUT = 10mA, TA = 25 C, 4.3V ≤ VIN ≤ 12V IOUT = 10mA, TA = 25oC, 4.5V ≤ VIN ≤ 12V IOUT = 10mA, TA = 25oC, 4.8V≤ VIN ≤ 12V IOUT = 10mA, TA = 25oC, 5V ≤ VIN ≤ 12V IOUT = 10mA, TA = 25oC, 6.5V ≤ VIN ≤ 12V IO = 10mA, VOUT + 1.5V < VIN < 15V, o TA = 25 C VIN = 3.3V, Vadj = 0,0mA < Io < 0.6A, o TA = 25 C (Note 3, 4) VIN = 3V, 0mA < Io < 0.6A, TA = 25oC (Note 3, 4) VIN = 3.3V, 0mA < Io < 0.6A, o TA = 25 C (Note 3, 4) VIN = 4V, 0mA < Io < 0.6A, TA = 25oC (Note 3, 4) VIN = 4.3V, 0mA < Io < 0.6A, o TA = 25 C (Note 3, 4) VIN = 5V, 0 ≤ IOUT ≤ 0.6A, o TA = 25 C (Note 3, 4) VIN = 5V, 0 ≤ IOUT ≤ 0.6A, o TA = 25 C (Note 3, 4) VIN = 5V, 0 ≤ IOUT ≤ 0.6A, o TA = 25 C (Note 3, 4) VIN = 8V, 0 ≤ IOUT ≤ 0.6A, o TA = 25 C (Note 3, 4) AP1115-ADJ/1.5/1.8 = 0.6A, ΔVOUT = 1%VOUT I 2.5/2.8/3.0/3.3/3.5/5.0 OUT AP1115-ADJ/1.5/1.8 (VIN -VOUT) = 5V 2.5/2.8/3.0/3.3/3.5/5.0 AP1115-XXX 0oC ≤ TJ ≤ 125oC o TA = 25 C, 30ms pulse Min Typ.

See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package. 4. Line and load regulation are guaranteed up to the maximum power dissipation of 5W. Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. 5. Quiescent current is defined as the minimum output current required to maintain regulation. At 12V input/output differential the device is guaranteed to regulate if the output current is greater than 10mA.
