Note:
1. This datasheet is downloaded from the website of Murata Manufacturing co., ltd. Therefore, it’ s specifications are subject to change or our
products in it may be discontinued without advance notice. Please check with our sales representatives or product engineers before ordering.
2. This datasheet has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product
specifications or transact the approval sheet for product specifications before ordering.
6.5 Output External capacitor
Ceramic capacitors are recommended as output external capacitor.
Using ceramic capacitors, small output variation and small ripple voltage are realized.
Output capacitor should be within 47μF to 1000μF. Output capacitor shall be placed near the output terminal.
When using plural capacitors, please make sure to place a capacitor of at least 47μF near the output terminal,
and place other capacitors near the load.
When using LC output filter, please make sure to place a capacitor of at least 47μF near the
output terminal.
7. Typical Characteristics Data
7.1 Load Transient Response
Our original ripple-detective control method achieves better load transient responses.
Vin=12V, Vo=1.8V, Io=8A ->16A, di/dt=2A/μs, Cout=100μF(Ceramic)
Fig.7.1 Load Transient Response
7.2 Output Impedance characteristics
Our original ripple-detective control method achieves very low output impedance in wide frequency range.
(Fig.7 shows the output impedance characteristics of MPDRX003S, which uses the same control method)
