Caution
1. A low-impedance capacitor suitable for switching applications must be used for the external capacitor and must be connected as close to the
IC as possible in order to assure low ripple voltage and stable switching operation.
2. The SI-881L/8911L series does not have a built-in overcurrent protection circuit on terminal V
O2
(–5V). Thus, avoid short-circuit conditions that
may cause an overcurrent.
3. Do not connect V
IN
(–) of SI-8811L to GND. The overcurrent protection circuit may not work if they are connected.
4. Terminals left unconnected in the connection diagram must not be connected to other circuits.
5. The IC's metallic heatsink is electrically floating. Do not connect it to GND or any other circuit.
6. Since the SI-8800L and 8900L series have an open-package construction, they can be operated in specific environments. Verify the operating
environment and use the IC within the conditions indicated in the reliability data.
