RP115L331D-E2 詳細描述
Product Overview
The RP115L331D-E2 from Nisshinbo Micro Devices Inc. is a single-output linear voltage regulator intended to provide a fixed positive 3.3 V rail with a maximum input voltage of 5.25 V. It is specified for 1 A output current and uses an 8-XFDFN exposed-pad surface-mount package, DFN1216-8. The device includes an enable control and protection against over-current, over-temperature, and reverse-current conditions. Its 0.17 V maximum dropout at 1 A and 160 µA quiescent current support compact power-supply designs, while the 75 dB PSRR at 1 kHz addresses supply noise rejection. The operating temperature range is -40°C to 85°C (TA).
Key Features
- Fixed 3.3 V positive output from a single linear regulator channel.
- 1 A output current capability with 0.17 V maximum dropout at 1 A.
- Maximum input voltage of 5.25 V.
- 160 µA quiescent current and 75 dB PSRR at 1 kHz.
- Enable control feature for controlled output activation.
- Over-current, over-temperature, and reverse-current protection features.
- Surface-mount 8-XFDFN exposed-pad package (DFN1216-8).
- Operating temperature range of -40°C to 85°C (TA).
Applications
- Fixed 3.3 V supply rails for microcontrollers, sensors, and digital logic interfaces.
- Compact power conversion stages in space-constrained electronic assemblies.
- Regulated 3.3 V rails in embedded control boards requiring enable-controlled output activation.
- Power delivery to supply noise-sensitive analog or sensor front-end sections where PSRR is relevant.
Design & Procurement Notes
Designers should confirm that the available input voltage remains within the specified maximum of 5.25 V and that the headroom supports the 3.3 V output under the required load, including the 0.17 V maximum dropout condition at 1 A. The fixed output provides one 3.3 V rail only, so system power budgets must account for this single channel. The 8-XFDFN exposed-pad package requires attention to land pattern, solder pad connectivity, and thermal dissipation, especially near the upper end of the -40°C to 85°C (TA) operating range. The enable control can be used to define output activation timing, while over-current, over-temperature, and reverse-current protection features should be considered in system-level fault handling. The 160 µA quiescent current and 75 dB PSRR at 1 kHz are relevant when balancing standby power consumption against supply noise rejection.
