General Description
The APL1187 is a low dropout three-terminal adjustable
regulators with 0.6A output current capability. In order to
obtain lower dropout voltage and faster transient
response, which is critical for low voltage applications,
the APL1187 has been optimized.
The device is available in 1.2V with an input supply below
9V. Dropout voltage is guaranteed at a maximum of 1.55V
at 0.6A.
Current limit is trimmed to ensure specified output current
and controlled short-circuit current. On-chip thermal
limiting provides protection against any combination of
overload that would create excessive junction
temperatures.
The APL1187 is available in the industry standard 3-pin,
SOT-89 and SOT-223 package.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which are fully
compliant with RoHS and compatible with both SnPb and lead-free soldiering operations. ANPEC lead-free products meet or exceed the lead-
free requirements of IPC/JEDEC J STD-020C for MSL classification at lead-free peak reflow temperature.
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.

Note 1: Stresses beyond the absolute maximum rating may damage the device and operating in the absolute maximum rating conditions may affect
device reliability.
Note 2: The maximum allowable power dissipation at any TA (ambient temperature) is calculated using: PD (max) = (TJ – TA) / θJA; TJ = 125°C. Exceeding
the maximum allowable power dissipation will result in excessive die temperature.

Note 3: See thermal regulation specifications for changes in output voltage due to heating effects. Load line regulations are measured at a constant junction
temperature by low duty cycle pulse testing.
Note 4: Dropout voltage is specified over the full output current range of the device. Dropout voltage is defined as the minimum input/output differential
measured at the specified output current. Test points and limits are also shown on the Dropout Voltage curve.
