(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) All voltages with respect to the ground pin, unless otherwise noted.

(3) The absolute maximum rating is V_INN – 0.3 V or –3 V, whichever is greater.

(4) The absolute maximum rating is V_INN – 0.3 V or –33 V, whichever is greater.

(5) The absolute maximum rating is V_INP + 0.3 V or 33 V, whichever is smaller.

(6) The absolute maximum rating is V_INP + 0.3 V or 36 V, whichever is smaller.

(7) The absolute maximum rating is V_INP + 0.3 V or 3 V, whichever is smaller.

(8) The absolute maximum rating is V_INP + 0.3 V or 2 V, whichever is smaller.

6.2 ESD Ratings

V_ESD	Electrostatic discharge	Charged-device model (CDM), per JEDEC specification JESD22-C101⁽²⁾	±500	V

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

6.3 Recommended Operating Conditions

\|V_INx\|	Supply voltage magnitude for either regulator	3.3		33	V
V_EN	Enable supply voltage	0		V_INP	V
V_OUTP	Positive regulated output voltage range	V_FBP		30	V
V_OUTN	Negative regulated output voltage range	–30		V_FBN	V
I_OUTx	Output current for either regulator	0.005⁽²⁾		150	mA

C_FFP	Positive channel feed-forward capacitor; connect from V_OUTP to FBP	0	10	100	nF
C_FFN	Negative channel feed-forward capacitor; connect from V_OUTN to FBN	0	10	100	nF
R_2P	Lower positive feedback resistor		10	240	kΩ
R_2N	Lower negative feedback resistor (from FBN to BUF)		10	240	kΩ
T_J	Operating junction temperature	–40		125	°C

(1) The nominal input and output capacitor value of 10-µF accounts for the derating factors that apply to X5R and X7R ceramic capacitors. The assumed overall derating is 80%.

(2) Minimum load required when feedback resistors are not used. If feedback resistors are used, keeping R_2x below 240 kΩ satisfies this requirement.

(3) For startup tracking to function correctly a minimum 4.7-nF C_NR/SS capacitor must be used.
