serially as ESR. For the bypass capacitor, a 0.33
μ
F capacitor placed as close to Vcc pin and GND pin as possible
is recommended.
Over- current Protection Circuit
The over-current protection circuits are built in at the outputs. They protect the IC from being damaged when the
load is short-circuited or subjected to an over current condition. This protection circuits perform holdback current
limiting.
Thermal Protection Circuit
A thermal shut down circuit (T.S.D.) is built into the IC to prevent damage due to overheating, Therefore, all the
outputs are turned off when the T.S.D. circuit is activated and are turned on when the temperature recedes to the
specified level. However, the T.S.D. circuit is only for extreme conditions and the regulator circuit should still be
designed for the IC not to exceed T
J
(max)=150
℃
.
Grounding
It is recommended that every capacitor (bypass and output capacitors) is grounded to PIN3 using single-point
connections.
Electromagnetic Fields
The IC is susceptible to strong electromagnetic fields and may cause malfunction. Therefore, caution should be
used when placing it on the PCB.
Protection Diodes
It is recommended that protection diodes be used when the output is connected to an inductive load.
