Notes: 1. The maximum Input Voltage of the ELECTRICAL CHARACTERISTICS is 5.25V. In case of exceeding this

specification, the IC must be operated on condition that the Input Voltage is up to 5.5V and the total

operating time is within 500hrs.

2. All of unit are tested and specified under load conditions such that TJ≈TOPT=25°C except for Output Noise,

Ripple Rejection, Output Voltage Temperature Coefficient and Thermal Shutdown.
