The ISL80103IRAJZ is a single-output low-voltage, high-current LDO with 2A and 3A output currents, respectively. These LDOs have an input voltage range of 2.2V to 6V and can provide output voltages ranging from 0.8V to 5V on the adjustable VOUT variants. Fixed output voltages of 1.8V, 2.5V, 3.3V, and 5V are available. On request, more unique voltage options are available.
An external capacitor on the soft-start pin provides adjustability for applications that require in-rush current less than the current limit. The ENABLE function enables the part to enter a low quiescent current shutdown mode. This product series uses a sub-micron BiCMOS technology to give best-in-class analog performance and total value.
In comparison to bipolar LDOs, this CMOS (LDOs) will consume much less quiescent current as a function of load, resulting in improved efficiency and the potential to explore packages with smaller footprints. To enable a leading class fast load transient response and hence a shorter overall AC regulation band for an LDO in this category, the quiescent current has been modestly reduced.
The ISL80103IRAJZ Pinout is shown as follows.
Pinout
| Pin Number | Pin Name | Description |
| 1, 2 | VOUT | Output voltage pin. |
| 3 | SENSE/ADJ | Remote voltage sense for internally fixed VOUT options. ADJ pin for externally set VOUT. |
| 4 | PG | VOUT in the regulation signal. Logic low defines when VOUT is not in regulation. Must be grounded if not used. |
| 5 | GND | GND pin. |
| 6 | SS | External cap adjusts in-rush current. |
| 7 | ENABLE | VIN independent chip enable. TTL and CMOS compatible. |
| 8 | DNC | Do not connect this pin to ground or supply. Leave floating |
| 9, 10 | VIN | Input supply pin. |
| EPAD | EPAD must be connected to copper plane with as many vias as possible for proper electrical and optimal thermal performance. |
