Caution Set the CS voltage so that the switch voltage (V_SW1) is equal to or greater than the
RESET detection voltage (−V_DET2).
Remark 1. The selection range is as follows.
V_RO, VOUT: 2.3 to 5.4 V (0.1 V steps)
−V_DET1: 2.4 to 5.3 V (0.1 V steps)
−V_DET2: 1.7 to 3.4 V (0.1 V steps )
−V_DET3: 1.7 to 3.4 V (0.1 V steps)
V_SW1:
+V_DET1 × 0.85 or +V_DET1 × 0.77
2. If a product with a voltage other than above is required, contact our sales representative.
