Ricoh R1141Q Series LDO Regulator Datasheet
The Ricoh R1141Q Series consists of CMOS-based voltage regulator ICs designed with high output voltage accuracy, low supply current, and low ON-resistance. These devices are suitable for power supplies in hand-held communication equipment due to their excellent line and load transient responses.
Key features include an embedded output current limit circuit to prevent breakdown from excess current and a chip enable circuit that realizes a standby mode with extremely small consumption current. The ICs utilize the SC-82AB (Super Mini-mold) package, enabling high-density mounting on boards.
