SK6513S
High Voltage, Low Power LDO
DESCRIPTION
FEATURES
⚫
⚫
⚫
The SK6513S is a high voltage, low power
consumption and high performance LDO. The family
uses an advanced CMOS process and a PMOSFET
pass device to achieve fast start-up, with high output
voltage accuracy. The SK6513S is stable with a 1.0 μF
~ 10 μF ceramic output capacitor, and uses a
precision voltage reference and feedback loop to
achieve a worst-case accuracy of 2% over all load,
line, process, and temperature variations.

FUNCTIONAL DESCRIPTION
Input Capacitor
A 1 μF ~ 10 μF ceramic capacitor is recommended to connect between IN and GND pins to decouple input power
supply glitch and noise. The amount of the capacitance may be increased without limit. This input capacitor must
be located as close as possible to the device to assure input stability and less noise. For PCB layout, a wide copper trace
is required for both IN and GND.
Output Capacitor
An output capacitor is required for the stability of the LDO. The recommended output capacitance is from 1 μF to 10 μF,
Equivalent Series Resistance (ESR) is from 5 mΩ to 100 mΩ, and temperature characteristics are X7R or X5R. Higher
capacitance values help to improve load / line transient response. The output capacitance may be increased to keep low
undershoot / overshoot. Place output capacitor as close as possible to OUT and GND pins.
Low Quiescent Current
The SK6513S, consuming only around 2.6 μA for all input range and output loading, provides great power saving in
portable and low power applications.
Short Current Limit Protection
When output current at the OUT pin is higher than current limit threshold or the OUT pin is short-circuit to GND, the
short current limit protection will be triggered and clamp the output current to approximately 100 mA to prevent
over-current and to protect the regulator from damage due to overheating.

NOTE:
Stresses beyond those listed under “ABSOLUTE MAXIMUM RATINGS” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those
indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SUNTEK
recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper
handling and installation procedures can cause damage. ESD damage can range from subtle performance
degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because
very small parametric changes could cause the device not to meet its published specifications. SUNTEK reserves
the right to make any change in circuit design, specification or other related things if necessary without notice at
any time. Please contact SUNTEK sales office to get the latest datasheet.
