ISL9000AMRNCEP is an enhanced version of the ISL9000AMRNCP and integrates two 100mA high performance LDOs, each channel IOUT is 50mA, TJ = +150°C. It has excellent transient response and can handle large current steps. ±1.8% accuracy under all operating conditions.
The ISL9000AMRNCEP is a high‑performance dual low‑dropout regulator (LDO) offering 100 mA per output, very low standby current, and excellent load regulation. It features individual Power‑On‑Reset and enable pins for each LDO, a programmable POR delay for VO2, and a reference bypass pin for noise filtering.
The device is supplied in a 10‑lead 3 × 3 mm DFN package and is targeted at handheld electronics such as PDAs, smartphones, portable instruments, and medical handheld devices. Detailed mechanical drawings and ordering information are provided for PCB layout and procurement.

|---|---|
| Quiescent current (both LDOs active) | 42 µA |
| Output voltage VOUT1 | 3.3 V |
| Output voltage VOUT2 | 1.8 V |
| Input voltage range | 2.3 V to 5.5 V |
| Dropout voltage @ 100 mA | 200 mV |
| Power‑Supply Rejection Ratio (PSRR) | 90 dB @ 1 kHz |
| Output noise | 30 µV rms @ 100 µA (1.5 V) |
| Operating temperature range | -55 °C to +125 °C |
| Package | 10‑lead DFN 3 × 3 mm (L10.3x3C) |
The quiescent current is typically only 42 µA with both LDOs enabled and active.
By connecting a timing capacitor to the CPOR pin, the POR delay for VO2 can be externally programmed.
VOUT1 is 3.3 V and VOUT2 is 1.8 V.
It is supplied in a 10‑lead dual‑flat‑no‑lead (DFN) package measuring 3 × 3 mm (L10.3x3C).
