ESD SENSITIVITY CAUTION
ESD damage can range from subtle performancedegradation to complete device failure. Precision
integrated circuits may be more susceptible todamage because very small parametric changes
could cause the device not to meet its publishedspecifications.

(1) Stresses above these ratings may cause permanent damage. Exposure toabsolute maximum conditions for extended periods may degrade device
reliability. These are stress ratings only, and functional operation of thedevice at these or any other conditions beyond those specified is not
implied.

1. Maximum output current is affected by the PCB layout, size of metal trace, the thermal conduction path between metallayers, ambient temperature and the other environment factors of system. Attention should be paid to the dropout voltage
when VIN < VOUT + VDROP.
2. The dropout voltage is defined as VIN - VOUT, when VOUT is 100mV below the value of VOUT for VIN = VOUT (NOMINAL) + 2Vor 6.3V, whichever is greater.
3. Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature
range.

APPLICATION NOTES
Input Capacitor and Output Capacitor
For proper operation, using a ceramic capacitor (CIN) between 1μF and 10μF between the input pin and ground. The input
capacitor must be located a distance of not more than 0.5 inch from the input pin of the IC and returned to a clean analogground. The capacitor with larger value and lower ESR (equivalent series resistance) provides better PSRR and linetransient response. The output capacitor must meet both requirements for minimum amount of capacitance and ESR in all
LDOs application for stable operation, use a ceramic capacitor (COUT) between 1μF and 10μF. Larger values in this range
will help improve load transient response and reduce noise. Output capacitors of other dielectric types may be used, but are
not recommended as their capacitance can deviate greatly from their rated value over temperature.
